Katie Finneran made a name for herself on stage, making her Broadway debut as an understudy in "On Borrowed Time," taking on the role of Sally Bowles in "Cabaret," and originating roles in new plays. Since then, Finneran has won two Tony Awards for her performances as Brooke Ashton in "Noises Off," and Marge MacDougall in "Promises, Promises." Finneran will once again head to television in the new comedy, "The Michael J. Fox Show." Finneran will portray Leigh Henry, Michael J. Fox's madcap sister. With her comic timing, that seems like a perfect match.
